Effect of irrigation with treated wastewater on geochemical properties (saltiness, C, N and heavy metals) of isohumic soils (Zaouit Sousse perimeter, Oriental Tunisia)

Distribution and accumulation of endocrine-disrupting chemicals and pharmaceuticals in wastewater irrigated soils in Hebei, China

“…Wastewater has increasingly been reclaimed and reused for agricultural irrigation due to scarce water resources, especially in arid and semi-arid regions (Klay et al, 2010;Palese et al, 2009;Rattan et al, 2005;Siemens et al, 2008). China is one of the countries with a severe water shortage problem and uneven water resource distribution.…”

“…This does not adequately address the possible risks to the environment and human health posed by the thousands of potential trace organic pollutants in reclaimed wastewater although these wastewaters (whether domestic or industrial) have been treated by municipal wastewater treatment plants. Many studies have been undertaken on inorganic compounds (e.g., Klay et al, 2010;Papadopoulos et al, 2009;Rattan et al, 2005;Smith et al, 1996) and pathogens (e.g., Mutengu et al, 2007;Palese et al, 2009;Pedrero and Alarcón, 2009) in wastewater and their possible effects on soil and plants as well as human health. Some studies have investigated some persistent organic contaminants such as polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in wastewater irrigated soils (e.g., Al Nasir and Batarseh, 2008;Chen et al, 2005;Sun et al, 2009).…”

Review the Environmental Effects of Using Industrial Wastewater Effluent (Case Study: Iran Qom Shokouhie Industrial State)

“…Jian Xu et al (2010) found that the important effects of using wastewater effluent in irrigation are related to soil physical and chemical change. Sami Klay et al (2010) also found that irrigation …”

“…It's shown that secondly sewage using for irrigation is suitable for crops that do not use raw. [10] studied about secondly sewage irrigation impact on soil's geochemical features in east Tunisia. They found that developed irrigation by infiltration sewage will increase salinity of soil and this salt will change soil's structure.…”

Global Experiences on Wastewater Irrigation: Challenges and Prospects

“…In Jordan, Al-Hamaiedeh and Bino ( 2010 ) concluded that soil leaching with fresh water was highly recommended, because it reduced the accumulation of salts and organic matter in the soil. The heavy metal indicates that their mobility and their adsorption will depend on the metallic contents of wastewater, organic carbon tenors, clay fraction and irrigation time in Tunisia (Klay et al 2010 ). Tarchouna et al ( 2010 ) showed that despite the very sandy texture of irrigated (with treated wastewater) soils studied, both saturated and unsaturated hydraulic conductivity exhibited a signifi cant diminution in the irrigated soil compared to the reference one in Mediterranean countries.…”
